having a problem installing mobo...

[nsyrax]

I just got m new mobo, an ASUS A8N-SL Premium mobo and when I went to hook up the power rto the mobo, I discovered that the cable from the power supply to the mobo, I realized that the power cable had 10-pins and th mobo had 14 slots. I have an ULTRA 500w power supply, do I have the wrong power supply? I can plug the cable in and it fits in, but there are still 4 slots left on the mobo and I sure as HELL am not turning that joker on unless I know for DAMN sure that I'm not gonna fry my new equipment. PLEASE HELP!!!!!

Plug in the PSU lead so with the side clip nearest you, the 4 holes are on the right.

My PSU has the same connector as yours and is plugged in that way.
I also have to plug another 4 pin power plug into a separate 4 pin socket on the motherboard.
The wire is Yellow and Black, for extra current on 12V.

If you dont have this extra connector, try it without.
Nothing will be damaged. It will either work or it wont.
